/* IOCTL information */
/*
 * List of ioctl/fsctl function codes that are or could be useful in the
 * future to remote clients like cifs or SMB2 client.  There is probably
 * a slightly larger set of fsctls that NTFS local filesystem could handle,
 * including the seven below that we do not have struct definitions for.
 * Even with protocol definitions for most of these now available, we still
 * need to do some experimentation to identify which are practical to do
 * remotely.  Some of the following, such as the encryption/compression ones
 * could be invoked from tools via a specialized hook into the VFS rather
 * than via the standard vfs entry points
